What is the correct LinkedIn page cover image size? [on hold]

I checked the size guide for LinkedIn cover images here

For page, they say:

1192 (w) x 220 (h) pixels (min)

1536 (w) x 768 (h) pixels (recommended)

Doubt 1: Both have different ratios. Why is that?

Doublt 2: When I opened developer tools, I found the dimensions of image container as 1128x191px. Which also has a ratio different to them.

So what is the correct ratio for the cover?
